According to MetSul, the heat bubble will bring a long sequence of hot days in Central and Northern Argentina. This increase in temperatures could also be felt in Uruguay and part of Brazil, specifically in Rio Grande do Sul.

The forecast is that several cities in the western half of Rio Grande do Sul will record highs of 36ºC to 39ºC at least until the middle of next week. The western border region of the state should have marks close to 40ºC.

In Porto Alegre and the North Coast of the state of Rio Grande do Sul, the days should get hotter until Wednesday or Thursday (8). In the valleys and in the center of Rio Grande do Sul, maximum temperatures are expected to exceed 35ºC in the coming days. The information is from UOL.

What is a heat blister?

  • A heat bubble occurs when areas of high pressure compress the air at the ground.
  • Hot air masses expand vertically in the atmosphere, creating a dome of high pressure that deflects weather systems, such as cold fronts, around them.
  • As the high pressure system settles over a region, the air below heats the atmosphere and dissipates the cloud cover.
  • The high angle of the summer sun combined with clear or low-cloud skies heats the ground even more.
  • The main effects of the phenomenon will be felt in Argentina, where temperatures should easily exceed the 40ºC mark, reaching up to 45ºC.
  • Argentina’s National Meteorological Service even issued red alerts for provinces in the west of the country and in northern Patagonia.
  • Meanwhile, in Uruguay, the maximum temperatures are expected to be between 34ºC and 38ºC.
  • The Uruguayan Institute of Meteorology also issued a heat wave warning for the next few days.
